Is Underglow Legal in Oregon? (2026 Guide)

Two rules are nearly universal across the US: no red light shown to the front and no blue underglow (both reserved for emergency vehicles), and no flashing, rotating, or strobing while driving. Beyond that, states differ. Here is how Oregon handles it.

Underglow rules in Oregon

• Colors: No red visible from the front (red only at the rear, plus a white plate light). Blue is prohibited (reserved for police). Avoid colors or patterns imitating emergency vehicles; white and amber are generally acceptable.
• No flashing: Steady burning only, no flashing, revolving, or oscillating, and it must not interfere with turn or brake signals.
• Driving vs parked: Usable while driving if steady and in non-emergency colors.

Underglow while parked or on private property

These laws generally govern vehicles on a public road or highway, so on genuinely private property, a private lot, driveway, car show, or off-road, underglow use is usually far less restricted. It is not a blanket "legal when parked" rule, though. A car parked on a public street is usually still treated as being on the highway, so the color limits (no red or blue to the front) still apply, and red or blue lighting can trigger separate police-impersonation laws regardless of whether the car is moving. Keep to compliant colors and check your local ordinances.

How to stay legal with underglow in Oregon

• Keep the lights steady-burning, never flashing, strobing, or rotating.
• Show no red light to the front, and avoid blue entirely.
• Do not mimic emergency-vehicle lighting or obscure your license plate.
• Confirm the current rule below and check locally before driving with it on.
